Novablast 4

Yes, for most runners the Novablast 4 fits true to size, so order your usual Asics size. The midfoot is snug and the heel locks down securely, while the toe box is medium width with enough room to splay your toes on a long run. If you have a broad forefoot, run in thick socks, or simply like extra room up front, going half a size up is a sensible option. There is no wide fitting in this version.

It can be a solid choice for marathon training and, for many runners, race day itself, especially if you value comfort and leg protection over outright speed. The deep, springy cushioning shines on long runs and keeps your legs fresh deep into the miles. It is not a carbon racer, so if you are chasing a sharp personal best you may prefer a plated shoe such as the Metaspeed Sky Paris. As a do-everything trainer that can also cover a steady marathon, it is well suited.

Yes, it is a friendly option for newer runners. The soft, bouncy cushioning is forgiving on the joints and makes easy running feel enjoyable, which helps when you are building a habit. The fit is comfortable and the upper needs no breaking in. The one thing to note is that it is a neutral shoe with a tall, soft platform, so if you overpronate or want a very stable, grounded feel, a stability shoe like the GT-2000 14 may suit you better as a first trainer.

Both share the same bouncy, high-stack daily-trainer DNA. The Novablast 5 is the newer model with the latest refinements to fit and foam, and tends to carry the current price. The Novablast 4 is the outgoing version, which often means better deals as retailers clear stock. If you loved a previous Novablast and want to save money, the 4 is a smart buy. If you want the freshest update and do not mind paying more, go for the 5.

For a soft, cushioned daily trainer it holds up well, and many runners get a typical 500 to 650km from a pair before the foam and outsole noticeably fade. The exposed foam areas of the sole can show wear faster than a fully rubber-covered outsole, so if you are a heavy heel-striker keep an eye on those zones. Used for its intended easy and steady miles rather than constant fast work, it should give you a dependable training-block lifespan.

It works well for walking and being on your feet thanks to the deep, soft cushioning and comfortable, no-break-in upper. The bounce that makes it fun to run in also makes it easy to stroll in. The only caveat is the tall, soft platform, which can feel slightly less planted than a flatter everyday shoe if you want maximum stability for long standing. For most casual and walking use it is a comfortable, supportive pick.
